Hope I'm not butting in here, but... Although I don't run systemd nor do I have an initramfs, the grub.conf entry for my LVM2 setup is just these two lines: title=Gentoo Linux 3.12.13 kernel /boot/kernel-x86_64-3.12.13-gentoo root=/dev/md5 net.ifnames=0 I've noticed several times (often much to my annoyance before I discovered what to do about it*) that starting of the raid arrays is automatic, apparently done by the kernel though I could be wrong about that. In fact I was astonished to find not long ago that I'd been running for a year or two with neither lvm2 nor mdraid installed! * SystemRescueCD and the Gentoo minimal installation CD both start any raid arrays they find and apply their own names to them. It is then impossible, or so I thought, to resume an interrupted installation process. Of course, all I had to do was "mdadm --stop /dev/md127" etc. -- Regards Peter
